Assassin to (hopefully) try and save the plot

You're an assassin in a book you hate to death. Your client just so happen to place a character/s (max 3) that is so rage inducing that you think the plot would improve better if they were a bag of bone 6ft under.
For fantasy assassins, yall have a very very SIMPLE powers. So yes, powers are allowed if it fits the world. So its up 2 u if you want powers/magic.

This time im going with the FL of Log in to Love City bcos i remember how rage inducing that ending was. Personally imma hang her on one of them meat hooks at her work after the job is finished. Smh no difficulty.
